Boltimate Core-Shell Columns

Boltimate Core-Shell Columns

Welch Boltimate is a core-shell material with a 1.7 μm diameter non-porous solid core, and a 0.5 μm porous outer shell. Boltimate can deliver speed and efficiency rivaling UHPLC, using conventional HPLC systems at much lower back pressure.

Highlights

  • Achieves efficiency similar to sub -2 μm materials (~200000 p/m)
  • High speed and high resolution
  • Compatible with both HPLC and UHPLC systems
  • Operates at low pressure, but is stable up to 600bar (8700 psi)
